The identification of this species with the Buccinum pyramid-ale Striim, 

 is somewhat uncertain ; if correct, the latter name has priority.

MANGELIA CERINA. (p. 432.)

 Kurtz and Stimpson, Proceedings of the Boston Society of Natural History, 

 vol. iv, p. 115, 1851 ; Stimpson, Shells of New England, p. 49, PI. 2, fig. 2, 1851. 



Shell elongated, fusiform, rather acute at apex, composed of about 

 seven whorls; apical whorls smooth, the others angulated in the middle 

 and decidedly flattened just below the suture ; suture distinct, but 

 shallow, undulated ; the body whorl has about eleven prominent, longi- 

 tudinal, sub-aciite plications or ribs, separated by wide, concave inter- 

 spaces. The ribs are most prominent at the angulation above the middle 

 of the lower whorl, and do not extend on the flattened sub-sutural band. 

 The whole surface is covered by fine, raised, revolving lines, often 

 alternately larger and smaller, separated by wider stria3, and crossed by 

 fine, distinct lines of growth, rendering them slightly nodulous. The 

 revolving lines are most distinct on the sub-sutural band, and are often 

 nearly obsolete over the summits of the ribs. Outer lip acute, with a 

 decided angle at about the posterior fourth, where it recedes to form a 

 decided, rounded notch, at and just above the angle; middle portion 

 nearly straight, gradually curving and receding toward the anterior end; 

 canal short, straight, and somewhat contracted. Color whitish, or 

 slightly yellow ; inner surface light wax-yellow.. Length, G.5 nira ; breadth, 

 O f aperture, 3 ml ".
